2.5 compared to 3.5 processor

[Binuclear]

I'm not that good with computers so I have no clue what the difference is between a 2.5 to 3.5 processor and a processor that is just 3.5. I've seen that on multiple computers and I plan on buying the HP Omen, so I just want to know what the difference is between the two.

 

[Darren]

I assume you're talking about clock speed, which is the speed that the processor operates at. The higher the better. Normally. There's variance in between different architectures and different companies (AMD and Intel).

And you also have to make sure your are comparing a dual core to dual core and quad core to quad core. If comparing a dual core to quad core then quad core is definitely better.

Those numbers mean nothing without context.

Which specific CPUs do they have?

 

[Geoff]

As beers said, speed alone is irrelevant without knowing what specific processors you're comparing. One could be a dual core to a 6-core, or an AMD vs Intel.

Guy's this is just a question my father brought to me. Supposedly he saw some computers that say 2.5 TO 3.5 processors and some that said just 2.5 or just 3.5 processor. He never brough up the units to me, just those numbers.

2.5 to 3.5 mean it's turbo boozed, like on the mobile Intel i7s

Also its in Ghz. Supposedly the website my father saw said that if you didnt have enough processing speed while gaming, it would add more. We both found this stupid, why wouldnt it just use all of it from the start?

Because new CPU's use something called turbo-boost, in which it automatically overclocks the CPU from stock frequency to a higher frequency when needed.

 

[tylerjrb]

The turbo boost on new CPUs are there to overclock the cpu when needed to a safe set speed set by Intel, amd etc. it doesn't run it all the time to save power and only uses the turbo boost when it is needed.

Quite a lot of the time it doesn't run at a solid ghz anyway again it runs lower to save power until needed.

Which CPUs have a 1GHz turbo boost on four cores?

 

[Geoff]

Which CPUs have a 1GHz turbo boost on four cores?

This. Most of the modern Intel CPUs have around a 400MHz turbo speed over their factory clock speed.

 

[tylerjrb]

there are a couple, i5-4690t for example.

If there is a 1GHz boost it is not on all 4 cores at the same time. Like Geoff said, generally around 400MHz on all 4. Higher boosts if only one or two cores.

Also depends on what was marketed on the label. Usually companies will lie/mislead consumers such as 2.5 GHz but boosts up to 3.5 GHz! even if only one core would be active at that clock rate.

No. As I said, that will never happen on four cores. Read the intel definition of Turbo Boost

Max turbo frequency is the maximum single core frequency at which the processor is capable of operating using Intel® Turbo Boost Technology
